Composite Action Technology
CFT’s composite metal decking is specifically designed to work in composite action with concrete slabs, creating an integrated structural system that maximizes strength while minimizing material usage. The deck serves as both formwork during construction and positive reinforcement in the finished floor system.
Composite Benefits
- Increased floor capacity with reduced concrete thickness
- Faster construction through elimination of formwork
- Superior bond between steel and concrete
- Reduced overall building weight
- Enhanced seismic performance
- Cost-effective structural solution
Design Features
- Precision-formed embossments for mechanical bond
- Optimized rib geometry for concrete placement
- Dovetail profile for maximum composite action
- Pre-galvanized steel for corrosion resistance
- Side lap connections for structural continuity
